just crack it open to see if it is a double yoke. Some times it is just a big egg with a lot of white.
But don't worry. You will get a lot more of these if it is a double yoke. My chickens lay them regular and it is not a breed thing. My ameraucana does it barred rock, black austrolorp rhode island red.
first I wanted to save it but after you get a couple, its the first egg that get chosen to eat because of the size. Yummy and enjoy
